To all whom it may concern:

Be it known that I, SAMUEL O. I-IARLAN, a citizen of the United States,residing at Lake City, in the county of Wabasha and State of Minnesota,have invented certain new and useful Improvements in Stove PipeThimbles, Collars, and Covers; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters of reference marked thereon, in which Figure l is aview showing the collar placed in proper position and a portion of thecover broken away. Fig. 2 is a view showing the thimble placed in properposition to receive the stove-pipe and the collar. Fig. 3 is an underside view of the collar, showing the lo cation of its retaining lngs.Fig. iis an under side view of the. cover, showing its retaining-lugs.Fig. 5 is a detached view of one of the movable lugs. Fig. 6 is asectional view showing the location of the different parts when thechimney-flue is closed.

The present invention has relation to stovepipe thimbles, collars, andcovers; and it consists in the different parts and combination of partshereinafter described, and particularly pointed out in the claimsSimilar letters of reference indicate corre sponding parts in all of thefigures of the drawings.

In the accompanying drawings, A represents the thimble, which issecurely attached to the chimney-aperture and is provided with theflange a, which flange extends a short distance beyond the edge of thechimney or its covering. This flange'a is provided with the notches orrecesses b, which are for the purpose of permitting the lugs c to bepassed between the fiange a and the chimneya In use the lugs c arepassed through the notches or recesses 19 and the collar B turned to theright or left, thereby bringing the lugs c behind or back of the flangea, which securely holds said collar in proper position.

The collar Bis provided with the aperture D, which is for the purpose ofreceiving the stove-pipe. For the purpose of closing the chimneyaperture when the stove-pipe is re moved, the cover E is provided. Thiscover is formed somewhat larger in diameter than the diameter of theaperture D, and is so formed for the purpose of lapping over the collar13. This cover is provided with the stationary or fixed lugs d, whichare for the purpose of engaging the collar B, as illustrated in Fig. 6The cover E is also provided with the movable catches d, which catchesare substantially of the form shown in the drawings. The inner ends ofthe catches d are attached to the shank c. This shank e may be formedintegral with the catches d; or, if desired, said shank may be formedseparate and attached in any well-known manner to the catches d.

The coverE is provided with the elongated slot f, which is for thepurpose of permitting the knob-shank passing through said cover toengage the shank e, and at the same time permitting the knob to be movedback and forth, which carries with it, by means of its shank and theshank e, the catches d.

In use, when it is desired to attach the cover E, the catches d aredrawn inward, at which time the fixed lugs d are passed under the collarB, when said cover is firmly seated against the collar and the catches(1 extended under the collar, thereby securely holding the cover inproper position.

For the purpose of covering the elongated slotf, the slide 9 isprovided, which slide is securely attached to the shank of the knob h.The slide g is formed large enough to cover the elongated slot f at alltimes.

For the purpose of preventing the catches d from becoming displaced, thestaples 71/ are provided, which are attached to the cover E in anyconvenient and well-known manner. These staples h also act as a stay toprevent the cover from slipping past the ap erture D,

Having fully described my invention, what I claim as new, and desire tosecure by Let ters Patent, is-

1. The combination of the thimble A, provided with the flange a, havingthe notches b, the collar B, provided with the lugs c, the

cover E, provided with the fixed lugs d, and In testimony that I claimthe above I. have IO the catches d and the knob h, substantiallyhereunto subscribed my name in the presence as and for the purpose setforth. of two witnesses.

2. The combination of thimble adapted to receive and hold a collar, thecover E, pro v SAMUEL C. HARLAN. vided with lugs d and the catches cl,the elongated slot f, the knob h, and the slide g, Witnesses:substantially as and for the purpose speci- E. A. 0. SMITH, fl d, F. W.BOND.
